None of the top three won their games this week, I hate weeks like this because of how that results with a big loss but it's also great because it gives odds a chance to recover. Bayern Munich is leading with nine points, that means they can lose three more games in a row, and they would still be at the top because they will probably have better averages then Leipzig.
This is why it's quite clear that they just simply didn't care about the game and nothing wrong with that at all. We are going to see things change a bit more and for that reason we are going to see Bayern play better. Why? Because after a draw, they play a lot better and try to shake things up and win some games in a row to get back at being on a good momentum for the season.
You are right it is frustrating when best teams do not win, but nine point lead that Bayern has is like safe space, and they can lose or draw without losing their top spot because they are so far ahead. Fact that they are so safe makes it look that they just did not care in game which happens when there is less pressure. Still, best thing is that bad game tends to wake them up, and we should think that Bayern will play much better next time, winning few games in row to get back their good speed during season, and recent draw is only small problem before they start winning again.
